Shrug and keep walking - it's only a little water!
Grumble a little but decide you'll pop in to a shop on your way in to pick up a new outfit
Hurl some obscenities at the driver and wave a fist but keep on walking - you'll be late if you don't
Do a 180 and head straight back to your house - you are not going in today
Finish it off - maybe it was just your choice that wasn't the best!
Finish it off - a little disappointed - and remember not to order what you did again
Eat some of it, but throw the rest away and go and buy a packet of crisps to fill yourself up
Vow never to go to that place again, throw your lunch in the bin and stay hungry for the rest of the day
Tell them it's fine and you can do it again, call the other two and arrange where to meet them
Sigh and say 'it's ok' then call your other friends and moan but agree to carry on and meet up anyway
Have a grumble at your cancelling friends, then call the other two and decide it's absolutely imperative that you remaining 3 represent and most definitely go out just to show the other 2 what they missed out on
Slam the phone down on your friends, call the other 2 and cancel on them. Decide you're going home to curl up on the sofa with a soppy film and a glass of wine
